  • Abstract

In this paper, we consider the class ofpolynomials $P(z)=a_{n}z^{n}+\sum_{\nu=\mu}^{n}a_{n-\nu}z^{n-\nu}$, $1\leq \mu\leq n$,having all zeros in $|z|\leq k$, $k\leq 1$ and thereby present an alternative proof,independent of Laguerre's theorem, of an inequalityconcerning the polar derivative of a polynomial.
